Terminals Function
Description
1 - 2
Aerial
- radio receiver aerial input
- aerial integrated into flasher; an external aerial can be used if desired
9 - 12
Step-by-step
input for devices which control movement. NO (Normally Open) contacts can be connected
9 - 10
Stop
- input for devices which lock or stop a movement: NC (Normally Closed) contacts may be connected
- for further details, refer to par. 8.1
9 - 11
Photo
- input for safety devices which when tripped reverse the gate's direction of movement: NC (Normally Closed)
contacts may be used
- for further details, refer to par. 8.1.
5 - 4
Flashing light
- flasher output (230 V auto-intermittent)
- flashes at regular intervals while the gate is moving: 0.5s on, 0.5s off
Warnings
• NC (Normally Closed) input: these must be shorted if not used; if more than one contact is to be connected to the stop input, they must be
connected IN SERIES;
• NO (Normally Open) input: these must be left unconnected if not used; if more than one contact is to be connected to the input, they must
be connected IN PARALLEL.
• Contacts must be mechanical and disconnected from any voltage.
Sensitive
edges
No specific input; use Nice equipment:
- fixed sensitive edges: use the TCE interface
- mobile sensitive edges: use the FT210 unit or IRW interface
Refer to the product’s instruction manual for details
